Valterra RV waste valve kit 3-inch with 72" flexible cable and folding handle, black

The Valterra TC372 Flexible Cable Kit is a 3-inch mess-reducing RV waste valve with a 72" flexible cable and folding handle for concealed, easy drain control.

Install a Valterra TC372 kit to move your waste valve to a safer, more accessible location without digging or replacing whole fittings. The flexible cable extends control from the valve body through compartments and bulkheads, while the folding handle lets you feed the assembly through tight openings and lock it in place. Built for universal compatibility with many RVs, campers, and trailers, this kit helps keep the valve protected from road damage and accidental opening.

How does the flexible cable prevent messy or exposed valve placement?

The cable lets you position the valve control inside a protected compartment instead of mounting the valve in a vulnerable external slot. By relocating the handle and control point, you reduce the chance of debris catching the valve or accidental openings from low brush and road impacts.

• 72" cable length provides multiple routing options inside storage bays or chassis.
• Folding handle feeds through small bulkhead openings for hidden placement.
• Compact valve body mounts in standard 3" openings used across RVs.

Can I use this kit to upgrade or replace an existing RV waste valve?

Yes — the TC372 is designed for universal fitment with many standard 3" RV waste systems and works well as an upgrade or direct replacement. Installation typically involves removing the old valve, positioning the new valve body, and routing the cable to the new handle location.

• 3" valve size matches common RV sewer outlet dimensions.
• Includes hardware to secure the folding handle during bulkhead installations.
• Works with common RV sewer plumbing layouts for straightforward retrofits.

What benefits does the folding handle offer during installation and use?

The folding handle reduces the bulk required to pass the control through narrow compartments and bulkhead holes, then unfolds for full leverage when operating the valve. Included nuts and fasteners lock the handle so it won’t flatten or slip during normal use.

• Fold-flat design for feeding through holes or tight storage areas.
• Locks in place to maintain handle rigidity when opening or closing the valve.
• Ergonomic shape for comfortable one-handed operation even with gloves.

How sturdy and durable is the kit for regular RV use?

Valterra builds the TC372 to withstand routine RV service conditions, with materials selected for corrosion resistance and repeated actuation. The flexible cable resists kinking while allowing smooth motion, and the valve housing is sized for common sewer fittings used in mobile applications.

• Durable cable resists bending fatigue and maintains consistent operation.
• Valve and hardware designed to handle frequent open/close cycles.
• Black finish helps hide dirt while providing a professional look.

Who is this for? The Valterra TC372 Flexible Cable Valve Kit is suited for RV owners, camper DIYers, and service technicians who want to relocate or replace a standard 3" waste valve for safer, cleaner operation. It's especially useful if your current valve is exposed to road hazards, difficult to reach, or if you prefer a concealed control inside a storage bay or compartment. Choose this kit when you need a practical, universally compatible upgrade that simplifies draining while reducing exposure and mess.
